Yeah I've done similar with sticking with training. If I plan to go for a jog I just put on my sport clothes after getting up, now that I wear my sport clothes I can go outside, now that I'm already outside in my sport clothes I can go for a little run. If at that moment I don't feel like running I just take a little walk.
Same with my workout, I usually do it at home, I just start small, do 10 push ups, see how it feels, if they feel good I can do another rep, if that felt good I can also do another exercise and before I really notice I've done my workout.
And if I don't feel like doing it I at least gave myself every opportunity to do it and I don't beat myself up for not doing it.
For eating healthier I figured out that for me it starts in the grocery store. For once I never go shopping hungry and if I just have healthy stuff in my fridge I am way more likely to eat better.
Well there's basically no way to leave a typical modern passenger plane once it's in the air. The doors lock in the frame from the inside and once the cabin is pressurized the pressure difference between inside and outside makes them impossible to open.
Actually there is one way - some windows on the flight deck can be opened sometimes and apparently exiting a passenger plane at traveling speed is survivable.
There's the story of British Airways Flight 5390 where the flight deck experienced a explosive decompression due to a faulty cockpit window and the captain was ejected out of the window partially, his knees got caught on the flight controls while his upper body stuck out of the window. Unable to pull him back in flight attendants held onto his legs for 20 minutes until the First Officer was able to perform a emergency landing. The pilot survived with - for what he has endured - minor injuries, he returned to flying 5 months after the incident.
